Answer:
3) 8
4) 5.25 cups
Step-by-step explanation:
3) cross multiply:
36 × 10 = 360
45 × x = 45x
equate them both:
360 = 45x
divide both sides by 45
360 ÷ 45 = 8
x = 8
4) 8 people : 3 cups of flour
14 people : how many cups?
14 ÷ 8 = 1.75
to get from 8 people to 14 people we multiply by 1.75, so do the same thing to the 3 cups:
3 × 1.75 = 5.25 cups
Answer:
38cm is the circumference
Explanation:
circumference = diameter x 3.14
diameter = 12
circumference = 3.14 x 12 = 37.68
Now we need to round to the nearest whole
36 and 38 are the nearest wholes to 37.68. We need to minus and then find smallest difference between the numbers; meaning the smaller the difference the closer it is.
37.68 - 36 = 0.68
38 - 37.68 = 0.32
37.68 is more closer so we can round this to 38.

Answer:
<em>-4/5,-1/2,-0.2,0.25</em>
Step-by-step explanation:
To order these, it would be best to convert them into decimals.
-4/5 is equal to -0.8
-1/2 is equal to -0.5
-0.8 is the least, because the further left on a number line, the less the number is.
-0.5 is next and then -0.2
Finally, 0.2 is the greatest
<em>-4/5,-1/2,-0.2,0.25</em>
<u>Hope this helps :-)</u>
